A system for indicating a locked state of a door of a vehicle is provided to allow a user to check whether the door of the vehicle is locked or unlocked, effectively, when the user wants to check the security state of the vehicle after parking the vehicle, through bio-directional wireless communication. When a vehicle controller(203) authenticates a first signal indicating that a door is locked or unlocked, a vehicle-controlling apparatus(200) transmits a second signal for changing a state of the door to be a locked state or an unlocked state to a BCM(Body Control Module)(300). When the vehicle-controlling apparatus receives a third signal indicating that the BCM normally operates, the vehicle-controlling apparatus transmits a fourth signal indicating that the state of the door is changed to a bio-directional wireless remote controller(100). The bio-directional wireless remote controller receives and stores the fourth signal, and transmits a fifth signal indicating that the fourth signal is finally received. The vehicle controller checks that the fourth signal is stored in the bio-directional remote controller, and then stores information about a changed state of the door when the door is changed to be locked or unlocked. |
